A series of medium-carbon low alloy steels was quenched to martensite and tempered at 150 C. This low-temperature-tempered (LTT) martensite was subjected to uniaxial tensile and impact testing. Yield and ultimate tensile strength and uniform elongation increased, and post uniform and total elongation and fracture toughness decreased, with increasing carbon concentration. The carbon dependence o...

Continued use of trastuzumab in PTEN-deficient HER2+ breast cancer induces the epithelial-to-mesenchymal transition (EMT), transforms HER2+ to triple negative breast cancer, and expands breast cancer stem cells (BCSCs). Using cancer cell lines with two distinct states, epithelial and mesenchymal, we identified novel targets during EMT in PTEN-deficient trastuzumab-resistant breast cancer. Diffe...

We present a systematic search for new neighbourhood stars among the Liverpool-Edinburgh high proper motion survey which we cross-identified with the DENIS survey. Their high proper motions ensure that they are not giant stars. The distances are estimated using DENIS photometry and we found that 100 stars probably lie within 25 parsecs from the Sun. They are mostly M-dwarfs, and 10 are probably...

Polychromatic and wavelength-selective neutron transmission radiography were applied during bead-on-plate welding on 5 mm thick sheets the face side of martensitic low transformation temperature (LTT) steel plates using gas tungsten arc (GTAW). The in situ visualization austenitization upon subsequent α’-martensite formation cooling could be achieved with a temporal resolution 2 s for monochrom...

Total hip and knee replacement surgery using metal alloy devices is common. Type IV allergic reactions to these implants occur, though infrequently. While uncommon, peri-implant metal allergic reactions may cause significant morbidity for the affected individual-including aseptic loosening, pseudotumor formation and frank device failure. It is challenging to predict who will have these reaction...

The focus of this review are allergic reactions to orthopaedic-surgical metal implants. The spectrum of metal implant associated potential allergic reactions encompasses eczema, impaired wound and fracture healing, infection-mimicking reactions, effusions, pain and loosening. Nickel, cobalt and chromium seem to be the predominant eliciting allergens. Despite the growing number of respective pub...

Editor—Although rare, perioperative anaphylaxis can lead to severe cardiorespiratory dysfunction or death. Numerous agents have been identified as triggers: the most common being neuromuscular blocking drugs, latex, and antibiotics. In contrast, sedatives, local anaesthetics, and opioids rarely cause anaphylaxis. The incidence of perioperative anaphylaxis ranges from 1:5000 to 1:25 000 and its ...

We report the discovery of a multi-planetary system transiting M0 V dwarf HD 260655 (GJ 239, TOI-4599). The consists at least two planets, namely b, with period 2.77 d, radius R$_b$ = 1.240$\pm$0.023 R$_\oplus$, mass M$_b$ 2.14$\pm$0.34 M$_\oplus$, and bulk density $\rho_b$ 6.2$\pm$1.0 g cm$^{-3}$, c, 5.71 R$_c$ 1.533$^{+0.051}_{-0.046}$ M$_c$ 3.09$\pm$0.48 $\rho_c$ 4.7$^{+0.9}_{-0.8}$ cm$^{-3}...
